It's sloppy on the key only. I've got it installed, for the time being. Strangely after tightening the cam eccentric and cam bolt the play is gone. But regardless I'm going to order a new timing chain and gear set. I'm just going to use the current setup to get the Pistons and rods assembled and then replace the timing set when the new set get here.
Well of course it's gone. You tightened the bolt down. You better believe it though when it's running, that cam sprocket will probably rock back and forth. That crap wouldn't be in any engine I built. Rock on, brother!
